2.2 Command format

General advice:

Commands can be entered in upper or lower case letters, they are not case‐sensitive, so either format can be used for input.

Each command entry must be concluded by a delimiter. This can either be a line feed (LF) or a semi‐colon (;).

If an end label is all that is sent to the WE2107, the WE2107 input buffer is cleared. The data provided in round brackets () for the commands are mandatory and must be

entered. Parameters in pointed brackets <> are optional and do not have to be provided.

The brackets themselves are not part of the input.

Text must be enclosed in quotes " ". Responses are given in ASCII characters and terminate with LF. Output in binary characters

is the exception here (see command MSV Each command comprises the command shortform, one or more parameters and the end

mark.

Responses consist of ASCII characters and close with CRLF. An exception to this is binary character output (see MSV Each command consists of the command shortform, one or more parameters and the delimiter.

and COF commands).

or COF).

Command shortform Parameter End label

Input ABC X,Y LF or ;

Output ABC? X,Y LF or ;

LF: line feed (lf = 0a hex)

Example: MSV?;

After this command, a measured value is output.

All the ASCII characters ≤ 20 parameters and the end mark.

For commands and parameters the following characters are allowed: ' ' '+' '‐' '.' ',' '"' '0' ...'9' 'A'...'Z' 'a'...'z' For a input string (command PST

the string is enclosed with " ...string...".

NOTE

If the master has send a command string (query), than the master has to wait for the answer before it send the next query.

If the master has send a command string (input), than the master has to wait for at least 10 msec. before it send the next query or command.

I1820-1.3 enHBM

2.3 Responses to commands

NOTE

Note on the reaction times of the WE:

The reaction times specified for the WE in the command description do not include the time taken to transfer the command to the WE and the time taken to transfer the response from the WE.

2.3.1 Responses to input

The WE works in an RS‐485 2‐wire bus configuration. No responses are given to input, regardless of whether the input is valid or invalid. After making an entry, use a query to

verify the input.

Example:

ASF3; //Setting the filter to level 3

If the master has send a command string (input), than the master has to wait for at least 10 msec. before it send the next query or command.

ASF?; //query the last input command

If the master has send a command string (query), than the master has to wait for the answer before it send the next query or command.

NOTE

If the parameter is a legal for trade parameter, and the legal for trade mode is switched on, than this parameter will not be changed.

I1820-1.3 en HBM

Page 16

WE2107 - Communication commands

2.3.2 Responses to parameter queries

A parameter query is entered by using the command with a question mark attached. A parameter query is always answered in ASCII format. The end label is a line feed

(LF = 0A hex). The output length of a query is always constant for every command.

Example:

Query: ASF; Response: 03 crlf

If the master has send a command string (query), than the master has to wait for the answer before it send the next query or command.

2.3.3 Responses to incorrect or unknown commands

The WE does not respond if a command is incorrect or unknown

I1820-1.3 enHBM

Page 17

WE2107 - Communication commands

2.4 Output types for measured values

The response to measurement queries (MSV?) depends on the output format (COF) that is set (binary or ASCII output). Data output works with fixed output lengths (see command

COF

Example:

Format command

COF0; MSV? Yy CR LF (y‐ binary) 4 COF2; MSV? Yyyy CR LF (y‐binary) 6

LF: line feed (lf = 0a hex), CR: carriage return ( = 0d hex)

The end mark of the data output is always a line feed. However, this character must not be filtered out as an end mark during binary output, as these characters may also be included in the binary code of the measured value. Which is why only the byte count is helpful with binary output.

2.5 Password protection parameters

WE password protection includes the important settings for the scale curve and its identifica tion. Commands with password protection are only activated after the password has been entered. Unless the password is entered via the command SPW be executed. A query is always possible.

WE2107 - Communication commands

3 Individual command descriptions

3.1 Interface commands (asynchronous, serial)

To establish communication between the WE and the computer, the interface has to be confi gured. The following commands are available in the WE to set up the interface and to select the transfer format:

D Communication address for bus mode ADR D Baud rate setting BDR D Output format for measurement data (ASCII / binary) COF D Select command for a bus user via the communication address (Select) S...

Characteristic data of the serial interface: Start bit: 1 Word length:8 bits Parity: none / even Stop bit: 1 Baud rate: 1200 … 38400 baud The asynchronous interface of the WE is a serial interface, i.e. there is serial transfer of data,

bit by bit and asynchronously. Asynchronously means that transmission works without a clock signal.

A start bit is set in front of each data byte. This is followed by the bits of the word (D0...D7), a parity bit for transfer checking and a stop bit.

1 bit Word length = 8 data bits 1 bit 1 bit

Start Parity Stop

1 character

Fig. 1: Composition of a character

I1820-1.3 enHBM

Page 21

WE2107 - Communication commands

As data transmission is serial, the rate at which data is transmitted must match the rate at which it is received. The number of bits per second is called the baud rate.

The exact baud rate of the receiver is synchronized with the start bit for each character transferred. The data bits then follow, which all have the same length. On reaching the stop bit, the receiver moves to the wait state until it is reactivated by the next start bit.

The number of characters per measured value depends on the output format selected (COF command).

Parameter backup With command TDD1;

Input Master ADR(P1),<“Fnumber“>; No response

Query Master ADR?; Response WE P1crlf P1=2 characters

Note: ( ) required parameters, < > optional parameters for parameter input

Function:

You only need this command when the WE is communicating via the RS‐485 bus. The command is used to prepare bus mode. Each WE connected in the bus must have a unique address (00 ‐ 31).

Parameter description:

Input: ADR(new address), <"serial number">;

The serial number (7 digits) can be included as an optional second parameter. The new device address will then only be entered for the WE with the specified serial number. When several WE's have the same address (initializing bus mode), this allows the device addresses to be changed without addressing several WEs.

As with the command IDN?, the serial number has to be specified in quotation marks.

Example: S98; Broadcast command

ADR25,"0000007"; allocates a new address,

only the WE with serial number 0000007 changes the address

Example: S31; Selecting the 'old' address (example)

Parameter backup With command TDD1;

Input Master BDR P1,<P2> No response

Query Master BDR?;

Response WE P1, P2crlf P1=P2= 1 character

Note: ( ) required parameters, < > optional parameters for parameter input

Function:

The command sets the baud rate for serial communication.

NOTE

When the baud rate is changed, communication is not possible at first. The computer also has to switch over to the new setting (baud rate). For the change in the baud rate to be permanent, it has to be saved in the EEPROM using the command TDD1.

Note on the evaluation of binary measured values

When measurement data is output in binary format, the binary code for CRLF may occur within the bytes representing the measured value. This is why the contents of the data output should not be tested for the CRLF character when checking for the possible end of measurement transmission. With binary output, it is far better to record the number of characters received. The CRLF control characters are also appended to the measured value during binary output.

Parameter description:

P1 is a 6-digit decimal number in the range 10000 to 120000 (=10 % ... 120 %). With P1=100000 (=100 %) this part load calibration is switched off.

P1 is a 6‐digit decimal number in the range 10000 to 99999 (=10 % ... 120 %) for none legal for trade applications.

P1 is a 6‐digit decimal number in the range 20000 to 99999 (=20 % ... 120 %) for legal for trade applications.

P1 is the percentage of the max. capacity with which the next LDW / LWT adjustment is to be carried out.

P1:= 100000 * adjustment weight / max. capacity

Example:

The scale curve LDW/LWT of a scale is adjusted with 15 kg=15000 d. But the only adjustment weight available for the adjustment is a 10 kg weight. Proceed as follows:

1. For the adjustment, set the CWT value to 66667 ( corresponds to 66 %).

2. For the adjustment, set the NOV value to 15000.

3. Then carry out an LDW/LWT adjustment.

After the adjustment, the WE outputs 10000 digits as the measured value at 10 kg and 15000 digits at 15 kg.

4. Set the increment to RSN5 and the decimal point to DPT3. This gives the number of

divisions as 3000 d=e and a display of 15,000 at 15 kg max. capacity.

NOTE

After an adjustment, the LDW and LWT values can be read out. They correspond to parameters, as if the adjustment had been carried out at max. capacity (and not at partial load). Should you want to enter the values for LDW and LWT again later, you must first enter CWT=0, then the LDW value that has been read out and finally the value read out for LWT.

When the factory default curve is entered with SZA/SFA, this resets the user curve to the default values LDW=0, LWT=200000 and CWT=100000.

The WE has the possibility to reduce the non linearity of the scale. The WE use a polynomial third order. Therefore two additional points between deadload (LDW) and max. capacity (LWT) has to be used for this correction. These commands should be set after the adjustment of the scale (LDW, LWT, NOV).

D Input values for the correction LIM D Output values of the correction LIN

To calculate the coefficients for the polynomial third order there are 4 pairs of values necessary:

Output values

0 0 Dead load removed

LIN1 LIM1 First point

LIN2 LIM2 Second point

NOV NOV max. capacity

So these two additional points have to be in the range 0…NOV. And the following conditions have to be valid:

Parameter backup With command TDD1 Input Master ASF(P1); No response Query Master ASF?; Response WE P1crlf P1 = 1 character

Note: ( ) required parameters, < > optional parameters for parameter input

Function:

The command selects a digital filter. This influences the filter behavior of the WE ( measurement signal bandwidth).

The limit frequency of the filter determines the settling time. The higher the filter index, the better the filter effect, but also the longer the settling time when the weight changes. Choose as low a filter setting as possible, but one that ensures measured value rest (standstill) when the weight does not change.

The mean‐value calculation influences the overall settling time of the WE. The overall settling time also depends on the mechanical construction of the transducer, the dead load of the scale and the weight to be weighed.
